in the vineyard : Climate
The Robertson Valley is characterised by cold winters and sunny summers, with an average annual rainfall of 350 - 400mm. In summer a fresh southerly breeze has a cooling effect on the vineyards, allowing the grapes to ripen evenly and in perfect balance. Nights are chilly and during summer months a mist often shrouds the vineyards until late morning. The dry climate and bracing breeze keep pests to a minimum, resulting in sparse spraying programmes.
Irrigation
Controlled computerised irrigation systems including the monitoring of soil moisture content ensure the vines are given exactly the right amount of water at the right time to produce grapes of optimum ripeness and developed flavours.
Soils
Rocky, mountain gravel soil with an abundance of free limestone and complemented with a slight clay component assisting in the water hold capacity of the soil. The high pH of the De Wetshof soils ensures ideal vineyard conditions for the growing of Chardonnay, allowing true varietal expression.
